摘要
目的:建立同时检测板蓝根中6个成分(尿苷、腺嘌呤、鸟苷、(R,S)-告依春、腺苷、直铁线莲宁B)的HPLC方法,考察双标线性校正(LCTRS)法对于板蓝根多成分定性分析的可行性。方法:采用HPLC法,以甲醇为流动相A,水为流动相B,梯度洗脱(0~3 min,3%A;3~18 min,3%A→14%A;18~25 min,14%A→26%A;25~34 min,26%A;34~40 min,26%A→46%A;40~60 min,46%A→90%A),流速0.8 mL·min^(-1),柱温30℃,检测波长为0~32 min,254 nm;32~60 min,230 nm,进样量10μL;测定板蓝根中6个成分在16根不同品牌和型号的C18色谱柱的实际保留时间,以鸟苷和直铁线莲宁B 2个成分作为双标化合物,采用LCTRS法定位各成分色谱峰,并用3根未知色谱柱进行方法验证。同时以鸟苷为参照物,采用RRT法预测其他5个成分的保留时间。比较这2种方法的预测准确性和色谱柱符合率。结果:LCTRS法能够较好地对6个指标性成分进行保留时间的预测和定性分析。与RRT法相比较,LCTRS法所预测结果准确性更高,色谱柱普适性更优。结论:LCTRS法用于同时测定板蓝根中多成分可行且准确,操作简便,耐用性好,具有推广价值。
Objective:To establish an HPLC method for the simultaneous determination of six components(uridine,adenine,adenosine(R,S)-goitrine,guanosine,clemastanin B)in Radix Isatidis,and to investigate the linear calibration with two reference substances(LCTRS)method for the qualitative analysis of multiple components in Radix Isatidis.Methods:HPLC method was used,with methanol as mobile phase A and water as mobile phase B.Gradient elution(0-3 min,3%A;3-18 min,3%A→14%A;18-25 min,14%A→26%A;25-34 min,26%A;34-40 min,26%A→46%A;40-60 min,46%A→90%A)was performed at a flow rate of 0.8 mL·min^(-1).The column temperature was 30℃,the detection wavelengths were 254 nm(0-32 min)and 230 nm(32-60 min).The injection volume was 10μL.The actual retention time of 6 components in Radix Isatidis was determined on 13 C_(18)chromatographic columns of different brands and models.Guanosine and clemastanin B were used as double reference compounds,and LCTRS method was used to locate the chromatographic peak of each component.Three unknown chromatographic columns were used for method validation.Using guanosine as a reference substance,the relative retention time method was used to predict the retention time of the other 5 components.The predictive accuracy and column coincidence of these two methods were compared.Results:The LCTRS method could effectively predict and qualitatively analyze the retention time of six indicator components.Compared with the relative retention time method,the LCTRS method had higher accuracy in predicting results and better column universality.Conclusion:The LCTRS method for simultaneous determination of multiple components in Radix Isatidis is feasible and accurate,with simple operation and good durability,and has promotional value.
